Electricity Transmissions Charges Continue To Spark Debate

The UK has set a legally binding target of achieving net zero by 2050. Doing that will require a significant increase in the use of renewable energy, but the way that generators have to pay for the cost of using the transmission network can be a real disincentive to investing in such projects.

Energy suppliers and generators pay transmission network operators for the right to use the transmission system, which includes the cost of maintaining and building the network's physical infrastructure. They then pass all of these costs on to billpayers. These 'TNUoS charges' (Transmission Network Use of System) total approximately £4.4billion per year.

The regulatory background to all of this is complex. Indeed, the Court of Appeal, which has plenty of experience with difficult and complex matters, has described the system as being of "byzantine complexity". And this matters, because TNUoS charges raise extremely important questions for renewable energy projects, both now
